What is BookStack?

Five security releases in four months, this one closing an import RCE

BookStack's release stream since v26.05 has been almost entirely security patches. This release fixes a range of issues: attachments updatable without permission, XSS through the drawing endpoints, draft endpoints altering non-draft pages, other users' drafts leaking into search results, remote code execution through crafted ZIP imports, and page visibility not updating in recycle-bin scenarios. The feature release it patches, v26.05, added a page contents view, tag API and separately controlled revision permissions.

What is SiYuan?

SiYuan enters a rapid alpha sprint, shipping calendar upgrades, transitive backlinks, and export extensions daily.

SiYuan is deep in pre-release iteration for v3.8.6, pushing multiple alpha builds per day. Recent work lands in three areas: calendar and scheduling (ISO week numbers, undated task scheduling, inbox-to-document insertion), knowledge graph depth (transitive backlink display, global reference sorting), and editor ergonomics (Markdown parsing performance, memory efficiency on long documents, customizable context menu shortcuts). The product continues to target power users who want local-first data ownership with a dense feature surface.

Five security releases in four months, this one closing an import RCE

◆ Current state

BookStack's release stream since v26.05 has been almost entirely security patches. This release fixes a range of issues: attachments updatable without permission, XSS through the drawing endpoints, draft endpoints altering non-draft pages, other users' drafts leaking into search results, remote code execution through crafted ZIP imports, and page visibility not updating in recycle-bin scenarios. The feature release it patches, v26.05, added a page contents view, tag API and separately controlled revision permissions.

◆ Where it's heading

The pattern is a substantial feature release followed by a run of point releases that are purely security, each crediting outside reporters. That cadence suggests sustained external scrutiny of the permission and import paths rather than a project shipping features in small increments. Every advisory in this run touches either permission checking or content handling on import and export — the two places where a self-hosted wiki with untrusted editors is most exposed.

◆ Prediction

Nothing in this stream points to the next feature release; on the current pattern the next tag is more likely to be another point release closing reported issues in the same permission and import surfaces.

6.3

SiYuan enters a rapid alpha sprint, shipping calendar upgrades, transitive backlinks, and export extensions daily.

◆ Current state

SiYuan is deep in pre-release iteration for v3.8.6, pushing multiple alpha builds per day. Recent work lands in three areas: calendar and scheduling (ISO week numbers, undated task scheduling, inbox-to-document insertion), knowledge graph depth (transitive backlink display, global reference sorting), and editor ergonomics (Markdown parsing performance, memory efficiency on long documents, customizable context menu shortcuts). The product continues to target power users who want local-first data ownership with a dense feature surface.

◆ Where it's heading

The v3.8.6 alpha cadence points to a stable release within days. Simultaneous effort on export fidelity (JavaScript embeds in PDF and image output), calendar promotion from visualization to scheduling tool, and AI agent capabilities (TypeSafe decision models visible in beta builds) suggests SiYuan is converging its PKM core with structured personal workflow management. The mobile editor is also receiving parity work alongside desktop.

◆ Prediction

The v3.8.6 stable release is the immediate next step given the alpha pace. A more deliberate announcement around the AI agent decision model integration — first surfaced quietly in the beta channel — is the likely follow-on, as it represents the most directional capability added in this cycle.
